Statements of Current States of the Art for Key non-Coronagraphic Technologies for HWO
Paul Scowen, Manuel Quijada, Emily Kan +7
In preparation for development of both key technologies and instrument concept studies to use those technologies, the Habitable Worlds Observatory Technology Maturation Project Off…
The Ultraviolet Type Ia Supernova CubeSat (UVIa): Science Motivation & Mission Concept
Keri Hoadley, Curtis McCully, Gillian Kyne +23
The Ultraviolet (UV) Type Ia Supernova Mission (UVIa) is a CubeSat/SmallSat concept that stands to test critical space-borne UV technology for future missions like the Habitable Wo…
Stability and photometric accuracy of CMOS image sensors in space: Radiation damage, surface charge and quantum confinement in silicon detectors
Michael E. Hoenk
Stability and photometric accuracy of silicon imaging detectors are essential for the Habitable Worlds Observatory and a range of NASA missions that will explore time domain astrop…
Hyperion: The origin of the stars A far-UV space telescope for high-resolution spectroscopy over wide fields
Erika Hamden, David Schiminovich, Shouleh Nikzad +30
We present Hyperion, a mission concept recently proposed to the December 2021 NASA Medium Explorer announcement of opportunity. Hyperion explores the formation and destruction of m…
Charge Coupled Device detectors with high quantum efficiency at UV wavelengths
Erika T. Hamden, April D. Jewell, Charles A. Shapiro +10
We report on multilayer high efficiency antireflection coating (ARC) design and development for use at UV wavelengths on CCDs and other Si-based detectors. We have previously demon…
Technology advancement of the CCD201-20 EMCCD for the WFIRST coronagraph instrument: sensor characterization and radiation damage
Leon K. Harding, Richard T. Demers, Michael Hoenk +15
The Wide Field InfraRed Survey Telescope-Astrophysics Focused Telescope Asset (WFIRST-AFTA) mission is a 2.4-m class space telescope that will be used across a swath of astrophysic…
Silicon Detector Arrays with Absolute Quantum Efficiency over 50% in the Far Ultraviolet for Single Photon Counting Applications
Shouleh Nikzad, Michael E. Hoenk, Frank Greer +8
We have used Molecular Beam Epitaxy (MBE)-based delta doping technology to demonstrate near 100% internal quantum efficiency (QE) on silicon electron-multiplied Charge Coupled Devi…
A system and methodologies for absolute QE measurements from the vacuum ultraviolet through the NIR
Blake C. Jacquot, Steve P. Monacos, Michael E. Hoenk +3
In this paper we present our system design and methodology for making absolute quantum efficiency (QE) measurements through the vacuum ultraviolet (VUV) and verify the system with…
UV anti-reflection coatings for use in silicon detector design
Erika T. Hamden, Frank Greer, Michael E. Hoenk +5
We report on the development of coatings for a CCD detector optimized for use in a fixed dispersion UV spectrograph. Due to the rapidly changing index of refraction of Si, single l…
Large Focal Plane Arrays for Future Missions
Paul A. Scowen, Shouleh Nikzad, Michael Hoenk +10
We outline the challenges associated with the development and construction of large focal plane arrays for use both on the ground and in space. Using lessons learned from existing…
